Simulation of Hyper veloce Impact using choc produced by laser for metals and inorganic materials – SiCLAMEN

The SiCLAMEN project focuses on the study of the behavior of matter under HyperVeloce Impacts (HVI) in a velocity range, so far barely explored (8-70 km/s). The proposed approach consists in developing the analogy between hyperveloce impacts and laser shocks. It will benefit from the versatility of the laser shocks, but also innovative diagnostics that have been recently developed on laser facilities. The SiCLAMEN project aims at simulating and studying in laboratory, hyperveloce impacts associated with space debris, optical protection, planetary defense and meteorites for geosciences and cosmochemistry. The last point will focus particularly on the controversy of dehydration induced during meteorite impacts. Understanding the effects of HVI on various metallic and inorganic “school” materials, will allow us to reproduce and study more complex natural materials and, for the first time in laboratory, ranges of velocity unreachable with conventional gas gun. Ultimately, an HVI platform based on laser shocks will be set up. The project will be structured around an interdisciplinary consortium (physics of laser material interaction, innovating diagnostics, mechanics, glass and geoscience). The complementary expertises will enable original approaches for mastering the HVI shock Laser analogy, the study of mechanical phenomena and physico-chemical transformations under impact.
